Methods for Separating Alloys: A Comprehensive Guide
Heap leaching is used to extract metals from large amounts of low-grade ore. In this process, the ore is stacked in large heaps, and a leaching solution is poured over it. As the solution trickles through the heap, it dissolves the metals, which are then collected at the bottom. Application: Primarily used for gold, copper, and nickel extraction.
